What does the surgical procedure called carpal tunnel repair remove?

The surgical procedure known as carpal tunnel repair primarily focuses on alleviating pressure on the median nerve, which is crucial for hand and finger function. This pressure is typically caused by the swelling of tissue within the carpal tunnel, which compresses the median nerve. During the surgery, the surgeon removes or cuts through a band of tough tissue (the transverse carpal ligament) to create more space in the tunnel, thereby relieving the compression.

The correct choice reflects this understanding: the procedure removes tissue that is contributing to the compression, which can include the thickened ligament causing the issue, but does not directly involve the removal of nerves or muscle tissue. This highlights the importance of addressing the structural aspects causing the carpal tunnel syndrome rather than removing the nerve itself or altering muscle tissue. Other options do not accurately capture the primary focus of the carpal tunnel repair procedure.
